Preheat your oven to 325°F (160°C). Apply a thin layer of grease to the bottom and sides of a 9-inch springform pan.
In a mixing bowl, combine the Oreo cookie crumbs and melted butter. Mix until the crumbs are evenly coated.
Press the mixture evenly onto the bottom of the prepared springform pan, forming a smooth layer. To press the crust firmly, use the back of a spoon or the bottom of a glass.
While you prepare the filling, just place the crust in the refrigerator to chill.
In a large mixing bowl, beat the softened cream cheese, granulated sugar, and vanilla extract until smooth and creamy.
Add the flour and mix until well combined.
Add one egg and beat well. Continue this process with each egg. Ensure each egg is incorporated well.
Add the sour cream, buttermilk, and red food coloring. Mix until the batter is smooth and evenly colored.
Pour the filling over the chilled crust in the springform pan, spreading it evenly with a rubber spatula.
In the preheated oven, place the cheesecake on the middle rack and bake for 60-70 minutes, or until the edges are set and the center is slightly jiggly.
Turn off the oven and leave the cheesecake inside for an additional 30 minutes to allow it to cool gradually.
Take out the cheesecake from the oven and put it to cool completely at room temperature.
Once cooled, refrigerate the cheesecake for at least 4 hours or overnight to ensure it sets properly.
Before serving, prepare the topping. In a mixing bowl, whisk together the heavy cream and powdered sugar until they reach a soft peak form.
Carefully remove the sides of the springform pan from the chilled cheesecake.
Spread the whipped cream over the top of the cheesecake, leaving a small border around the edges.
Garnish the top with Oreo cookies, either whole or crushed.
